To understand the reproductive processes of freshwater crabs of the genus Potamon, we examined the first and second gonopod and the gonoducts of the female by histological methods. The gonopods are highly modified compared to those of other brachyuran crabs. In particular, the second gonopod is unus
The adult ovary of the branchiuran Argulus japonicus is a single, median, long sac-like organ located in the thorax above the alimentary canal. A long germarium, including oogonia, very early previtellogenic oocytes, and young somatic cells (interstitial cells), is embedded in the dorsal ovarian wal
Glossiphonia heteroclita has paired ovaries whose shape and dimensions change as oogenesis proceeds: during early previtellogenesis they are small and club-shaped, whereas during vitellogenesis they broaden and elongate considerably. During early oogenesis (previtellogenesis), each ovary is composed
